Refer to Maintenance Scheduling → Regular Service Intervals → Regular Service Intervals: 2012 FLTRXSE. Inspect filter element at proper intervals and service as required. Under dusty conditions, inspect more often.

WARNING

Do not use gasoline or solvents to clean filter element. Flammable cleaning agents can cause an intake system fire, which could result in death or serious injury. (00101a)

NOTICE

Install air filter before running engine. Failure to do so can draw debris into the engine and could result in engine damage. (00207a)

The high flow air cleaner has a cotton gauze filter element and water-resistant rain sock.

Riding a motorcycle equipped with an exposed oiled air filter under wet or rainy conditions is NOT recommended. Install the rain sock over the filter element under these circumstances.

NOTE

The use of cleaning, drying or oiling methods or products other than those shown will damage the filter and void the manufacturer's warranty.
K&N AIR FILTER CLEANER and K&N AIR FILTER OIL are available from a Harley-Davidson Dealer, either as part of the FILTER CARE SERVICE KIT or sold separately.
DO NOT OVER-OIL THE AIR FILTER. Over-oiling may interfere with the proper performance of the engine and/ or certain engine components. If oil is still draining or dripping from the filter media twenty minutes after oiling, clean and re-oil the filter element.

1.	See Figure 1. Loosen hose clamp (4) and separate the filter assembly from the air inlet tube.
2.	Remove four screws (2) and remove the ring (3).
3.	Remove filter element from cover (5). NOTE The chrome back plate is adhered to the element and is provided with a replacement element kit should one be needed.
4.	Gently tap the element to dislodge any loose dirt, then gently brush with a soft bristle brush.
5.	Spray air filter cleaner liberally onto the cotton filter media and let soak for ten minutes, OR roll the cotton filter media in a shallow pan of air filter cleaner. Remove immediately, and let soak for ten minutes.
6.	Rinse the filter media from the inside with low-pressure tap water.
7.	Shake off all excess water and let the filter media air-dry. DO NOT use compressed air or a heat gun to speed drying.
8.	Inspect filter. Replace the filter element if damaged or if filter media cannot be adequately cleaned.
9.	After the filter media is completely dry, EITHER spray air filter oil along each pleat, once only, holding the spray nozzle approximately 76 mm (3 in) away from the media, OR carefully use a squeeze bottle to deposit oil along each pleat, once only. Let the oil wick (absorb) into the filter media for twenty minutes before proceeding.
10.	After twenty minutes, inspect the filter media, and carefully apply oil to any remaining visible white spots on the filter media, and allow to absorb.
11.	See Figure 1. Verify the foam pad (9) is in place in air filter cover and assemble the filter element assembly into the air filter cover (5).
12.	Orient the Screamin' Eagle logo to face the outside and align notch (8) in filter back plate as shown in inset. Install ring (3) and tighten screws (2) to 1.7–2.3 N·m (15–20 in-lbs)
13.	Place clamp (4) onto rubber snout with worm drive (7) approximately centered in notch and screw slot facing down.
14.	Install the air filter assembly to the mark on the intake tube (approximately 16 mm (⅝ in)). NOTE Hold worm drive in approximate center of notch when tightening clamp.
15.	Rotate so the Screamin' Eagle logo faces out and verify the air filter assembly does not touch any other parts. Tighten the clamp to 5.1–6.2 N·m (45–55 in-lbs).
